Question

the equation of a line given as x Cos 120 degree + y Sin 120 degree equal 3 draw a rough sketch of the line showing alpha and P where symbols have their usual meaning

Answer 1

Steps are given below to draw the graph.

Step-by-step explanation:

Here, take α as the angle and the numeric value (3) as P.

Steps are:

1. Make a table where in first row, write α in the first column and P in another one.
2. Below Put the value of α as 0⁰, 30⁰, 45⁰, 60⁰, 90⁰ and calculate the corresponding values in the column of P.
3. Now make X and Y axis in the graph paper and mark these points α and P in the graph.
4. Join the values in a curve form or in a straight line as it is forming.
5. Hence, equation of line is formed.
